摘要： Flat, quadrangular permanent magnets m18, m28, m38 are disposed on a yoke 20 with their magnetic pole faces facing upward and so as to be adjacent to one another or contact one another, and such that magnetic pole faces of different polarities are disposed alternately. A vibrating membrane 26 is disposed on a top surface side of the yoke 20 so as to be parallel to the magnetic pole faces of the permanent magnets. Coil pairs L18, L28, L38, which are wound in helical forms and are disposed at front and reverse surfaces of the vibrating membrane, are disposed on the vibrating membrane 26 so as to correspond to the permanent magnets m18, m28, m38. The coil pairs L18, L28, L38 are wound in helical forms so as to be formed substantially similarly to outer edges of the magnetic pole faces of the permanent magnets m18, m28, m38. Inner peripheries of the helices of the coil pairs are disposed at outer sides of regions which include positions corresponding to centers of the magnetic pole faces, and outer peripheries of the helices of the coil pairs are disposed so as to overlap one another. Because the permanent magnets are disposed on the yoke so as to be adjacent to or contact one another, magnetic flux traveling in a direction substantially parallel to a surface of the vibrating membrane becomes a maximum, and interlinks with the coil pairs. When current is supplied to the coils, a direction of force which the current receives from a magnetic field is a direction substantially orthogonal to the surface of the vibrating membrane, and force in a direction along the surface of the vibrating membrane becomes extremely low. Thus, noise components can be reduced such that sound quality can be improved.
摘要翻译：扁平的四边形永磁体m18，m28，m38设置在磁轭20上，其磁极面朝上并且彼此相邻或彼此接触，并且使得不同极性的磁极面交替设置。振动膜26设置在磁轭20的上表面侧，以平行于永久磁铁的磁极面。螺旋形缠绕并设置在振动膜的前表面和反面的线圈对L18，L28，L38设置在振动膜26上，以对应于永磁体m18，m28，m38。线圈对L18，L28，L38以螺旋形式缠绕，以与永磁体m18，m28，m38的磁极面的外边缘基本相同地形成。线圈对的螺旋的内周设置在包括对应于磁极面的中心的位置的区域的外侧，并且线圈对的螺旋的外周被设置成彼此重叠。由于永久磁铁配置在磁轭上以便彼此相邻或彼此接触，所以在基本上平行于振动膜的表面的方向上传播的磁通变得最大，并且与线圈对相互连接。当向线圈提供电流时，电流从磁场接收的力的方向是与振动膜的表面大致正交的方向，并且沿着振动膜的表面的方向的力变得非常低。因此，可以降低噪声分量，从而可以提高声音质量。
